Notably, compounds 12–14 can be described as a 3D open–framework with nano–channels, compound 15 can be described as a 3D open–framework with double helical channels, while compound 16 can be described as a 3D heterochiral coordination polymer with double helical channels, which can be obtained by spontaneous resolution from the racemic phosphonic acid.X–ray powder diffraction analysis shows that compound 16 is a pure phase. Surface photovoltage spectroscopy of compound 16 indicates that it possesses positive SPV response in the range of 300–600 nm and shows p–type semiconductor characteristic.
